I'm not sure there is much to do. What do you mean by what can you do, did you have some thoughts about what you think you want to do? As always, when you part way and/or do your exit interview, be professional. Say thanks for the opportunity, that you learned a lot, and answer questions honestly and with tact/compassion. Standard nice things to say when you leave include a) this place is great, but I'm passionate about the new opportunity, and want to give it a shot, b) it's both a great opportunity to do new interesting work and earn more money, c) thanks for all the fish. Temper any negative things you say greatly - if you have some useful feedback for your old boss at exit interview, give it... but don't burn bridges, and don't say anything that's not actionable. Be concrete with any exit feedback... like "I would have liked to have more code reviews from senior developers" is good, but "the code is spaghetti and I hate working on it" is not great.
